Enabling the Capability of Passively Creating BFD Sessions on the Egress

Enabling the Capability of Passively Creating BFD Sessions on the Egress


On a unidirectional LSP, creating a BFD session on the active role (ingress node) triggers the sending of LSP ping request messages to the passive role (egress node). Only after the passive role receives the ping packets, a BFD session can be automatically set up.

Perform the following configurations on the egress node of an MPLS TE tunnel.


  1. Run system-view

    The system view is displayed.

  2. Run bfd

    The BFD view is displayed.

  3. Run mpls-passive

    The capability of passively creating BFD sessions is enabled.

    After this command is run, a BFD session can be created only after the egress receives an LSP Ping request containing a BFD TLV from the ingress.
